Specific implementation mode
The direct foam cleansing product of the present invention includes being combined from the distribution of sprinkling distributor with the cleaning for forming direct foam
Object." direct foam " used herein or " direct products " they are the products that foam is formed on the surface of its application, without
Need additional physics, chemistry or similar intervening measure.For example, once product is distributed from its container, on the surface by hand
Frictional product generates foam, which is not direct froth pulp.The container that direct froth pulp is directly stored from it applies
On the surface.
Cleaning compositions can be distributed from distribution system according to the present invention.As described in detail below, distribution system
System includes the container for liquid cleansing composition and the distributor for being connected to container.Suitable container can be request for utilization
People'sThe container of the bag of technology type in bottle.Distributor includes pump, precompression valve and buffer.Precompression valve control
The minimum pressure that system needs liquid from distributor release, and liquid is pumped into and is pumped out buffer by damper mechanism control
The maximum pressure that chamber needs.When composition is distributed from the distribution system of the present invention, cleaning compositions, which provide, to be had shown in Fig. 1
Wide cyclic annular foam pattern direct froth pulp.However, other foam pattern forms are designed by the nozzle of distributor
Modification be expected and can realize.
With reference to figure 2, distributor 1 is shown, direct foamed cleaning composition of the invention is from wherein distributing.Distributor
1 includes the sprinkling engine framework 10, buffer chamber 30, precompression valve 40 that liquid inlet 16 is fluidly connected to pump chambers 20
With nozzle 50.Liquid composition 100 is advanced through flow path 200 shown in Fig. 3 and is assigned as direct froth pulp.Liquid enters
Mouth 16 can be fluidly connected to optional dip tube 18 (not show from bottle or liquid storage device by the flow path 200 of sprinkler 1
Go out) extract liquid composition 100.Bottle and liquid composition 100 individually can sell or be provided as direct foamed cleaning production
The alternative of product.Liquid composition 100 from liquid storage device can also be drawn into sprinkler 1 in the case of no dip tube 18
In, for example, using it is known with collapsible internal structure (if bag is in bottle) without air system, such as applicant
The layering bottle of bottle technology or be known in the art other without air technique.
Distributor 1 may include actuating element, trigger 14 as shown in Figure 2 or other known actuating element
(such as button) is mechanically connected to piston 22.In operation, living when spring-loaded trigger 14 is activated by user
Plug 22 moves down, and when trigger 14 discharges, the power of spring moves back up piston 22.This extends the volume of chamber and production
The raw low-pressure for opening inlet valve 12, closing outlet valve 36 and liquid composition 100 being caused to suck pump chambers 20.In inlet valve 12
When opening, outlet valve 36 closes (outlet valve is moved upward to closed position by low-pressure).
When trigger 14 is activated or pulled in by user, trigger 14 generates down stroke in pump chambers 20.Under piston 22
It moves and leads to liquid push-in in the exit passageway 60 of precompression valve 40.Buffer chamber 30 is also connected to the exit passageway 60.
Inlet valve 12 is closed and outlet valve 36 is opened, and is thus allowed liquid composition 100 to pass to exit passageway 60 and is passed to precompression valve
40.When the pressure that the down stroke of pump piston 22 generates is more than the fracture pressure of precompression valve 40,41 flexible deformation of diaphragm of valve
And valve moves into its open position.Then liquid towards spout 50, liquid are assigned as foam at nozzle.
When trigger 14 activates, inlet valve 12 is closed, and the liquid from pump chambers 20 is prevented to be pushed back into bottle/liquid storage device
In (pressure is moved downward to closed position).This permission establishes pressure in exit passageway 60 and buffer chamber 30.Cause
It is more than the maximum output of nozzle 50 for the displacement volume of pump, down stroke phase of the pressure in exit passageway 60 in pump piston 22
Between rise.
The pressure acts on resiliently compressible variator 70, and variator is arranged in buffer chamber 30, is used for
Change the available space of buffer chamber.In this embodiment, variator 70 includes buffering piston 32 and engaging piston
Buffer spring 34.
The pressure of liquid composition 100 in buffer chamber 30 pushes down on buffering piston 32, and slow
Therefore the buffer spring 34 for rushing 32 lower section of device piston compresses, thus increase the available space of buffer chamber 30 and allow liquid
Provisionally (pressurization ground) is stored in buffer chamber 30 body composition under stress.
There is overflow openings (not shown) at the certain depth of buffer chamber 30.This is finished to prevent fluid pressure
Foundation too much, and thus this be it is a kind of it is specific restriction point at outlet, cannot be downward more than its buffering piston 32
It advances.As a result, when the movement of buffering piston 32 is more than specified point (at greatest hope pressure/spring force), liquid can pass through
Overflow openings in the wall of buffer chamber 30 are flowed back into liquid storage device.Liquid flooding opening can be arranged for buffering
The pressure of largest buffer spring 34 in device chamber 30, such as 0.5 to 3.0 bar or 0.5 to 1.0 bar, in precompression valve 40
It is default to open on pressure or fracture pressure.In an exemplary embodiment of the present invention, this precompression valve open pressure can be with
It is such as 1.5,2.5,3.5 or even 6 bars or more.In a preferred embodiment of the invention, open pressure 2 and 4.5 bars it
Between, more specifically about 3 to 3.5 bars.
It should be noted that in an exemplary embodiment of the present invention, precompression valve 40 has less than can be in buffer
The opening pressure of the maximum pressure formed in chamber 30.By this method, buffer chamber 30 be filled up completely full liquid and by
Before this reaches its maximum pressure, precompression valve 40 can be opened, and spray and can fully occur.This allows continuous sprinkling feelings
Condition.(nozzle is by by nozzle when more specifically, obtainable liquid is more than the liquid that nozzle 50 can spray in sprinkler
Maximum flow rate limits), remaining liq is stored in buffer chamber 30 and is gradually discharged until pressure drop by certain time
It is closed under pressure to precompression valve, this can cut off liquid flow.This allows by the long-time sprinkling of single actuation and by tool
There is the continuous sprinkling of certain activation interval repeatedly activated.For example, if nozzle 50 can only spray 1ml/s and once activate
The liquid of middle pumping 1.4ml, sprinkling can continue 1.4 seconds.If the actuating three times of the liquid of 1.4ml will pump in 2 seconds, sprinkling
Device can continue sprinkling 4.2 seconds.
The control of precompression valve 40 is acted from the sprinkling of nozzle 50.Precompression valve 40 has the pressure limited；In the pressure of liquid
When power is more than the pressure of this restriction, precompression valve is opened and generates sprinkling.The pass of the restriction of precompression valve 40 is dropped down onto in pressure
When closing under pressure, precompression valve is closed, and to ensure that the liquid only properly to pressurize can march to nozzle 50, is ensured continuous
Sprinkling.Due to the fluid pressure in exit passageway 60 and buffer chamber 30, precompression valve 40 is opened, and liquid combination
Thus object 100 is transmitted to nozzle 50, create desired sprinkling.
As described above, when trigger 14 activates, inlet valve 12 is closed, prevent the liquid from pump chambers 20 be pushed back into
Enter in bottle/liquid storage device.Although distributor 1 can be in subsequent triggering release and liquid sucking step, liquid composition
Body 100 still is able to by precompression valve 40 and by aperture 50 to continue to spray.By this method, user can cause continuously to spray
Spill-as long as user continuously moves back and forth trigger 14 so that liquid suction stroke is able to catch up with spraying, liquid composition 100 is continuously taken out
Go out and is sent to pressure chamber and precompression valve.In this regard, it is noted that by changing pump chambers 20 and buffer chamber
The Relative volumes of room 30 can design various rate of pumpings.
Referring now to Figure 4, showing nozzle 50, there is the fluid spinner axis being placed in liquid discharge channel 42
44.Rotator shaft 44 leads to spin chamber 52 in an end in adjacent nozzles aperture 55.Rotator shaft 44 is along towards aperture
55 downstream direction axially extends.Tapered expansion area 58 is led in aperture 55, and the sprinkling angle of the liquid in aperture 55 is exited in guiding
Degree.
With reference to figure 5, nozzle 50 includes multiple eddy flow slots 54 and provides the aperture 55 of the exit path by nozzle 50.Eddy flow
Slot 54 can be counted as one to five, three to five or three.In the inside of nozzle 50, eddy flow slot 54 guides liquid
Into inner funnel or cone 56, the funnel or cone terminate at its narrow end into short cylindrical shape aperture 55.
As shown in figure 11, rotator shaft 44 does not extend fully into spin chamber 52.In fact, the end face of rotator shaft 44
45 are spaced apart with the bottom 57 of the centre bore 59 of nozzle 50.By this method, partially liq is not forced to flow through eddy flow slot 54, but
These eddy flow slots can be bypassed and flow through the inner funnel of nozzle or bore 56 center.Thus liquid flow is made of two tributaries, and one
A circulation overwinding chute 54, and a stream passes through center, with different speed.It is not wishing to be bound by theory, it can be false
If fair speed stream can be carried secretly compared with low velocity stream so that the entire main body for flowing to the liquid of nozzle orifice is energized.It is this
Arrange that the final result observed is the improvement of foam characteristic.
Eddy flow slot 54 can be in shape, in width and depth change, and can leniently arrive narrow tapered to be hindered in minimum
The best acceleration of liquid flow is adapted in the case of power and pressure drop.Inner cone 56 can be with about 20 ° to about 150 ° of angle, preferably
About 50 ° to about 120 ° of ground, and more preferably about 100 °.Inner cone 56 limits how many rotating liquid before aperture 55 further
Accelerate, and how wide the sprinkling for therefore limiting expansion or being come out from aperture 55 is.Eddy flow slot 54 accelerates and liquid is made to beat under stress
Precession enters in inner cone 56, further compresses in continuously decreasing diametrically at inner cone and accelerates liquid, under high pressure
It is sprayed away by narrower bore mouth 55.Unexpected pressure drop in the exit in aperture 55 allows the liquid of high compression and excitation
It expands and liquid is broken into droplet.Speed, direction and the spray width of drop are sprayed by eddy flow slot 54 and inner cone 56
Angle introduce energy and track limit.It should keep as short as possible in short cylindrical shape path technique in aperture 55, with not
Influence the width of sprinkling.
Outside in aperture 55 or the downstream in aperture, are equipped with the breathing space of 58 shape of outer cone, and aperture is exited in guiding
Liquid drop spray angle.The outer cone 58 can with about 20 ° to about 120 ° of angle, preferably about 30 ° to about 90 °,
And more specifically about 50 °.Outer cone 58 is further equipped with multiple ventilation orifices 51.In exit, unexpected pressure drop generation is being sprayed
Spill the low-pressure in center.The low-pressure can be sucked from environment in air to sprinkling.As a result, the droplet formed in exit
It is transformed into another typical material bubble.The effect is further enhanced by outer cone 58, and outer cone is also guided liquid flow outward with further
Sprinkling is broken into wide foam spray pattern.Foam beads can be by via close to the placement of highest lower pressure region
Ventilation hole 51 in outer cone 58 introduces more air further to adjust.Via Venturi effect, which can suck more
More air enter in drop stream, generate thicker, more significant foam.
Aperture 55 can have constant diameter or can be tapered in an axial direction, spray from the proximal end of nozzle 50 (i.e.
Closest to aperture 55 and flow path 200) when marching to distal end, expand in diametrically.Invariable orifice diameter can be about
0.10mm is to about 0.60mm, or about 0.30mm is to about 0.40mm, or about 0.32mm is to about 0.37mm, or about 0.36mm.At cone
When shape, aperture 55 can be from the proximal diameter of about 0.13mm to about 1mm to the distal diameter of about 5mm, to about 0.10mm to about
0.60mm or about 0.30mm to the distal diameter of about 0.40mm and it is tapered.
Exemplary nozzle construction provides in table 1.
Table 1
As described above, pump, buffer and nozzle are arranged such that liquid can be distributed with the pressure in relatively narrow bandwidth.
The lower limit of distribution pressure is determined by the fracture pressure of precompression valve 40.20 1 generations are pumped higher than the pressure of fracture pressure, precommpression
